Completed Lab Write-up (data tables, graphs, and conclusion) due before 2 PM, the following Wednesday.

Course Objectives:

University-Level Competencies:

General Physics II introduces students to the role of scientific reasoning in solving introductory physics problems using algebra & trigonometry (e.g. calculating entropy changes in thermodynamics, calculating magnetic field due to electric currents, and analyzing circuits). They will apply the scientific methodologies of inquiry during the laboratory, PHYS 202L, and write well-reasoned conclusions. They will also be introduced to the history of scientific discovery (e.g., topics and devices are introduced with historical perspectives) and learn that the theories in physics evolve into laws after continuous re-evaluations and arguments. In addition they will see how scientific advances made in a laboratory transform into useful technological devices (e.g., the development of the transistor from vacuum tube to silicon chip).

Lab Reports:  At the completion of each lab every student is required to turn in a lab write-up with a conclusion. Students are encouraged to be creative with their conclusions and explain whether or not their results are accurate. If the results are not close to the accepted values, student are expected to give reasons for any discrepancies. The conclusion section is the part of the lab which is most important to check for student comprehension of the topic.

How to write a conclusion?

* Conclusion is the most important part of your report. It is a brief summary-paragraph, about half a page, primarily reflecting about the laboratory experience. You must write your own conclusion, after completing the data collection and analysis. It must be written as the last piece and attached as the last piece, after data tables and graphs.

* Conclusion should state things that are unique for your investigation which can be accomplished by including values of the experimentally determined physical quantities.  Just remember that you cannot write your conclusion without completing your experiments or investigations. General statements like "I have determined the densities of given solids" and "Human Error" are not acceptable.

Conclusion Points are listed for 10 point total lab report score:

* Start your conclusion by re-stating the purpose with appropriate changes (0.2 pt). Then you need to briefly state (don’t repeat procedure) how you conducted the experiment and collected the data (0.2 pt). Continue this with summarizing your results (make it unique by listing your experimental values) (0.2 pt), referring to the data tables and graphs when appropriate, and answer the purpose (0.2 pt). Then you need to discuss about some of the difficulties you had, errors and their possible causes, and suggestions for improvement (0.2 pt). Describe your reasoning using physics terminology and principles and reflect extensively. You should explain as completely as possible what goes through your mind that leads you to your conclusion.
